Question

25. Point A on a coordinate grid is at (3, 4). If the point is reflected across the line

Answer 1

Using translation concepts, the images of the points are given as follows:

25. (4,3).

26. (3,1).

What is a translation?

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

The rule for a reflection across y = x is given by:

(x,y) -> (y,x).

Hence, in item 25:

The image of (3,4) is (4,3).

The rule for a reflection across y = -x is given by:

(x,y) -> (y,-x).

Hence, in item 26:

The image of (-1,3) is (3,1).
